Abstract

The report explains the calibration procedure of the HOPLAB facility. A short description of the facility is first included concerning the mechanical structure and its equipment in terms of sensors, transducers and relevant electronic instruments. A detailed explanation of the calibration procedure is next presented, which is principally centred at calibrating the force measurements along the input and output bars with a certified load cell. The main issues and problems connected to this particular testing rig are discussed. Finally an example of a typical elaboration, starting from raw experimental data to obtain the force-displacement curve of a specimen in tension, is provided.
